### Android example
To compile example to shared library you will need [Android NDK](https://developer.android.com/ndk/downloads/index.html).
To build Android apk you will need [Android SDK](http://developer.android.com/sdk/index.html#Other).
Export path to Android NDK, point to location where you have unpacked archive:
export ANDROID_NDK_HOME=/opt/android-ndk
Add toolchain bin directory to PATH:
export PATH=${ANDROID_NDK_HOME}/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin:${PATH}
Export sysroot path:
export ANDROID_SYSROOT=${ANDROID_NDK_HOME}/platforms/android-16/arch-arm
And compile shared library:
CC=arm-linux-androideabi-gcc \
CGO_CFLAGS="-D__ANDROID_API__=16 -I${ANDROID_NDK_HOME}/sysroot/usr/include -I${ANDROID_NDK_HOME}/sysroot/usr/include/arm-linux-androideabi --sysroot=${ANDROID_SYSROOT}" \
CGO_LDFLAGS="-L${ANDROID_NDK_HOME}/sysroot/usr/lib -L${ANDROID_NDK_HOME}/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/ --sysroot=${ANDROID_SYSROOT}" \
CGO_ENABLED=1 GOOS=android GOARCH=arm \
go build -tags static -buildmode=c-shared -ldflags="-s -w -extldflags=-Wl,-soname,libexample.so" -o=android/libs/armeabi-v7a/libexample.so
To build apk export path to Android SDK, point to location where you unpacked archive:
export ANDROID_HOME=/opt/android-sdk
And build apk:
./gradlew assembleDebug
If everything is successfully built apk can be found in android/build/outputs/apk/debug directory.
